Summary:To provide a technique capable of realizing a switching machine to which excessive conversion force is not applied almost at the end stage of switching process while securing the required conversion force.SOLUTION: A switching machine 2 switches a turnout by moving a switch roller 69 along a predetermined route on that the switch roller 69 moves while being engaged with a cam surface of a switch cam 11 of an operating lever 10. A timing belt 63 is stretched between a driving pulley 61 and a driven pulley 62 such that the switch roller 69 is fixed to the belt with a supporting member. The switch roller 69 is moved along an operating direction of the operating lever 10 by rotation of the driving pulley 61 and the driven pulley 62 in the switching process.SELECTED DRAWING: Figure 1 【課題】必要とする転換力を確保しつつ、転換過程の終期付近に過剰な転換力が作用しない転てつ機を実現することができる技術を提供すること。【解決手段】転換ローラ６９が動作かん１０の転換カム１１のカム面に係合しながら移動する所定経路に沿って転換ローラ６９を移動させることで分岐器を転換させる転てつ機２である。原動プーリ６１と従動プーリ６２とにタイミングベルト６３を架け渡し、当該ベルトに支持部材で転換ローラ６９を固定する。転換過程において原動プーリ６１と従動プーリ６２の回転により、転換ローラ６９は動作かん１０の作動方向に沿って移動される。【選択図】図１
